Re: Stus-List Hitachi 55A alternator question - 12.63 v output...

[Russ & Melody via CnC-List]

Hi Dave,
Many years ago I had low voltage on alternator 
output and found it to be a bad diode in the 
rectifier... just one more thing to check.

        Cheers, Russ

Hi All,Â
I have a yanmar 2GMf20 with what I believe is 
the stock 55 amp alternator.   I noticed that 
my ACR was not combining batteries, which led me 
to research a bit then measure the voltages on 
each bank, and then at the alternator “Batt” terminal. Â
Irrespective or RPM or battery state, the 
voltage at the BATT terminal does not exceed 
12.63 in operation.   (he ACR therefore 
doesn’t “see” a charging state)  The belt is new and not slipping.Â
This suggests and alternator or regulator 
problem.   Does this make sense?  Is there anything else I should check?
If I end up replacing the regulator, are there 
better options for this alternator than stock?

Thanks All.

Dave
